NICHOLAS V. MAZZOCCHI, OF NEW YORK, N. Y.

GAS-BURNER.

' resident of the .city of New York, in the county of New York and State of `New York, have invented certain new and useful Improvements in Gas-Burners, of which the l following is a specification.

This invention relates lto burners operative by a 'fluid fuel used in connection with stoves or ranges.

My main object is to provide a burner of this character in which all outlets receive a substantially equal share of the fuel supply, so that they all burn with substantially equal intensity.

Another object is to `provide in a burner of thisl character means for directing a flame against a particular desired portion yof the stove or range without interfering With the burning of the `other pipes of the burner and without reducing the efficiency of the burneras a whole.

A further object is to provide a burner of the character described which shall be simple and cheap` in construction and uniform, efficient and economical in operation.

Al still `further `object is to provide in a burner of this character an outlet pipe which shall be cheap to manufacture and adapted to be directly fitted to the nipple without tapping or threading.

A further objetc is to provide a burner of the character described which shall economically and efficiently permit of the burning of one or several complete rows of pipes independently of the others.

Other objects and advantages of this invention will appear from the detailed description and the features of novelty will particularly be pointed out in the claims:

In the drawing accompanying this specification and forming a material part thereof,

-1-a of Fig. 2 showing the sectional construction of my improved burner, and the means for directing the flame against a particular portion of the stove without interfering with the operation of the remaining burners.

Referring in detail to the drawing I have there shown a range 15 of the French type having the fire pot 16 and the oven 17. i

My burner is secured within the range by any suitable means such as the brackets 18, and is made up in separate sections comprismg end mixing chambers 19, the central chamber 20, and the intermediate chambers 21. Extending from these chambers are the nipples 22 for the burner pipes 23. As will be clear from Figs. 3 and Al these pipes are cast in one piece formed with a flanged connecting end 24 adapted to fit over the nipples. In practice an air tight joint may be obtained by applying a thin layer of cement on the inner surface of the connecting portion. .This construction docs away with the necessity of tapping the connecting end of the pipes and threading `the nipple, and thus affords a great saving in labor and expense.

The end sections 19, are made sloping at the top as at 35 and the nipples Q2 Iextend therefrom at a gentle angle so that the end rows of burners 23 project a flame against the walls 26 of the oven. It will be noted that the directing of the flame against the walls of the oven is accomplished by a principal and independent row of burner pipes, and not by branch pipes at an angle to a main line of burners. The latter construction has been resorted to but found, inefficient so that the fuel supply divides itself very unequally between the main and branch pipes. The central burners are veitical and heat directly the heat retaining balls shown at 27. I preferably mold these heat retaining balls in one cluster made up of continuous rows as shown. This is preferable to supporting individual balls on rods, as has been done heretofore, since the rods soften unlder the heat and stay together with the ba s.

I am aware that to thus direct the ame at an angle against the walls of the oven is not new but in constructions heretofore made this has been accomplished at the eX- pense of a reduced fluid pressure for thev remaining burner pipes which prevented them from burning properly. In the present invention this diiiculty is obviated by the independent sectional construction.

To further assure that Vall of the burner pipes in a given section will receive a substantially equal pressure supply, I give the mixing chamber the construction shown in Fig. 3. As will be clear from this figure number as that in the central section.

L up too much space or material.

the typical mixing chamber is formed with an enlarged front portion having an open ing 29 for the fuel supply and a narrowed rear portion 30 thus providing a bafde wall 3l. In the constructions heretofore had i baiile wall 31. The fuel under the pressure is then reflected and distributed equally among the burners of the section.

From F ig. 2 it will be obvious that I make my end sections 19 preferably L shaped and the intermediate sections 21 shorter than the central section 20. The elbow of the L is made to carry an extra pipe which together with the burners of the shorter -section form a row of burner pipes of the same this way the burners may be operated independently of kthe others and without taking clear the back burner on the L may be opi' eratedy although the remaining burners in As will be the shorter section are shut 'oft'. The sections may be held together by any suitable means such as the straps 32 and the dowels 33.

Having thus described my invention, I claim l. A burner comprising a plurality of 'seotions constituting mixing chambers, the central section being of greater length than the intermediate sections and the end sections being shaped sov as to be disposed alongside and across the end of said intermediate sectionsso as to complete the length ofthe latp tions constituting mixing chambers, said mixing chamberscomprising a wideportion terminating in an inclined wall adapted to` serve'a's a baiile and a narrower tapered porsectionbeing of greater length than Ltlhe'intermediate sections and the end sections being shaped soas to be disposed alongside and across the end of said intermediate sections so as to complete the length of the latter, equal to that ofthe vcentral sections. a
